function [S]=mexBM_from_setting(S,S0);
% function creates statistics "S" from given structure S0.
%
% This example is extremely simple - BM does not have any attributes of its own
%
% Compulsory attributes are:
%  S0.name = "...";                             % optional name 
%  S0.drv = struct('names',...,'sizes',...)     % ID of input signals (see object RV)
%  S0.rv  = struct('names',...,'sizes',...)     % ID of posterior values (see object RV)
%  S0.posterior  = struct('mu0',...)            % initial value of statistics (is processed by mexEpdf)


S.posterior=struct(); % create empty structure for posterior
